Description
Technical field
The present invention relates to car body sealing techniques, more particularly to one kind of Vehicle De L'Avant Blinde By Creussot crew module and speed changer cover
Compound sealing structure.
Background technique
Bearing-type panzer car body is generally divided into piggyback pod and crew module by armour plate welding forming.In order to overhaul bottom
The power part (such as engine, speed changer) of disk, improves the maintenanceability of vehicle, usually needs to increase inspection inside crew module
(cover) is built, this relates to the sealing problem of access cover (cover) and car body.Good sealing can waterproof and dustproof, partition makes an uproar
Sound improves man-machine efficacy, improves environment inside car comfort.Access cover and the traditional sealing means of car body are to add spiral shell using flat rubber mat
The structure type connect is tethered, frequent leak is not able to satisfy the sealing performance of vehicle requirement.
Summary of the invention
The object of the present invention is to provide the compound sealing structures of a kind of crew module and speed changer cover, are able to satisfy it both
The requirement of vehicle maintenanceability, and can guarantee the seal request of crew module.
Realize that the technical solution of the object of the invention is as follows:
A kind of compound sealing structure of crew module and speed changer cover, including car body crew module, speed changer cover and sealing strip, it is described to multiply
There is opening in member cabin in the position of corresponding speed changer, and opening is formed with ladder, and cascaded surface is the mounting surface connected firmly with speed changer cover,
There is the first seam allowance perpendicular to mounting surface at the edge of ladder, and the speed changer cover covers on the opening of crew module, speed changer cover
Oral area has L shape flanging, and as the mounting surface connected firmly with crew module, speed changer, which covers on the inside of oral area, is approximately higher than the first of crew module
Stop portion is equipped with the second seam allowance perpendicular to speed changer cover inner wall；The crew module connects firmly with speed changer cover, the two mounting surface it
Between accompany the first sealing strip, be separately installed with the second sealing on the first seam allowance of crew module and the second seam allowance of speed changer cover
Item.
Preferably, the second seam allowance of the first seam allowance with speed changer cover of the crew module is spatially close is mutually perpendicular to.
Further preferably, second sealing strip has collet portion and elastomeric seal portions；In the first stop portion, the second sealing
The collet portion collet of item on the first seam allowance, elastomeric seal portions be embedded in the first seam allowance, crew module mounting surface and speed changer cover in
In the U-shaped space that wall three surrounds, it is sealed；In the second stop portion, the collet portion collet of the second sealing strip is in the second seam allowance
On, in the space that the second seam allowance of elastomeric seal portions insertion, speed changer cover inner wall and the first seam allowance surround, it is sealed.
Description is the respectively it is found that a whole set of compound sealing structure of the invention uses three-layer sealed through the above structure
At the installation faying face of two stop portions, the first stop portion and crew module and speed changer, compact-sized, simple installation safely may be used
It leans on, sealing when particularly suitable armored vehicle is paddled meets vehicle requirement.
Detailed description of the invention
Fig. 1 is crew module and speed changer cover scheme of installation.
Fig. 2 is the partial enlarged view of the compound seal of Fig. 1.
Fig. 3 is car body crew module seam allowance and sealing strip scheme of installation.
Fig. 4 is speed changer cover seam allowance and sealing strip scheme of installation.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
Referring to Fig. 1, this structure is mainly by car body crew module 1, speed changer cover 2, the first and second sealing strips 6,7, and first and second
Seam allowance 4,5 forms.
Referring to Fig. 3, crew module 1 has an opening in the position of corresponding speed changer, and opening is formed with ladder 11, cascaded surface be with
There is the first seam allowance 5 perpendicular to mounting surface at the mounting surface that speed changer cover 2 connects firmly, the edge of ladder.
Referring to fig. 4, speed changer cover 2 covers on the opening of crew module 1, and the oral area of speed changer cover 2 has L shape flanging 21, makees
For the mounting surface connected firmly with crew module 1, speed changer cover 2 is approximately higher than at the first seam allowance 5 of crew module 1 perpendicular to change on the inside of oral area
Fast 2 inner wall of device cover is equipped with the second seam allowance 4.
Crew module 1 with speed changer cover 2 is connected firmly by bolt, and the two accompanies the first sealing strip 6 between mounting surface,
Mounting surface has enough rigidity and flatness.
Second seam allowance 4 of the first seam allowance 5 of crew module 1 and speed changer cover 2, which spatially approaches, to be mutually perpendicular to.In crew module
The second sealing strip 7 is separately installed on 1 the first seam allowance 5 and the second seam allowance 4 of speed changer cover 2.
Referring to Fig. 1, the second sealing strip 7 has collet portion 71 and elastomeric seal portions 72.At the first seam allowance 5, the second sealing
For 71 collet of collet portion of item on the first seam allowance, elastomeric seal portions 72 are embedded in the mounting surface and speed changer of the first seam allowance, crew module 1
It covers in the U-shaped space that 2 inner wall threes surround, is sealed；At the second seam allowance 4,71 collet of collet portion of the second sealing strip exists
On second seam allowance, in the space that second seam allowance of the insertion of elastomeric seal portions 72,2 inner wall of speed changer cover and the first seam allowance surround, carry out
Sealing.
The mounting surface of 2 the two of crew module 1 and speed changer cover has enough rigidity and flatness, and the first seam allowance 5 is using punching
Pressing formation, the second seam allowance 6 are shaped using integral cast, can effectively reduce the installation error of two kinds of sealing strips.
